Attachment Tapes

Aavid attachment tapes adhere heat sinks to a heat source while offering good thermal characteristics. They are extremely quick and easy to apply and require no curing time. These tapes can be electrically conductive or isolating and need no mechanical support to provide thermal or physical contact between the device and heat sink. Tapes are ideal for adding heat sinks after you have spun your board as use does not require a board change.

Pre-applied attachment tape are available with Aavid heat sinks to cut down on assembly time and costs. Tapes are available in custom cut size or in sheet size, typically 8.00" x 8.00".

Ther-A-Grip 1090 / T412

Ther-A-Grip 1090 uses an expanded foil carrier coated on both sides with
high-bond strength, presure sensitive acrylic that is loaded with titanium diboride particles.
The combination of filter, expanded metal and embossed surface enhances both tape conformability and thermal performance.

T410R / T411

For plastic packages

T410R thermally conductive tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a 0.002 inch (0.05mm) aluminum foil carrier.
The other side of the foil carrier has a silicone pressure sensitive adhesive which provides excellent adhesion to silicone-contaminated plastics and other low energy surfaces.

T411 thermally conductive tape consists of a high bond strength, pressure sensitive adhesive with an aluminum mesh carrier layer.
The mesh carrier allows the tape to conform to curved surfaces of plastic molded IC packages, providing a high adhesive strength attachment for heat sinks. The high performance silicone-contaminated plastics and other low energy surfaces.
